I wrote such code that imports multiple files:
Folder = 'Data';
FileList = dir(fullfile(Folder, '**', '*.txt'));
Strings = cell(1, numel(FileList));
for iFile = 1:numel(FileList)
File = fullfile(FileList(iFile).folder, FileList(iFile).name);
Strings{iFile} = load(File);
end
In Data folder I have files like:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/795329/image.png)
The problem is they don't have any extension (simple Ascii format of numbers that can be easily open with notepad).
Is there any option to import "any" file type or files without extension?
I have tried this, but it gives me an error.
FileList = dir(fullfile(Folder, '**', '*.*'));
%or
FileList = dir(fullfile(Folder, '**', '*.data.1'));
Any suggestion? I would appreciate any help

@Mateusz Brzezinski - what is the error message when you try to use either of the last two lines of code? Does your Data folder have folders or just files? If just files, then you may be able to use
FileList = dir(Folder)
to get a list of all files in that folder.

Simpler:
P = 'Data';
S = dir(fullfile(P,'**','*'));
S = S(~[S.isdir]);
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
S(k).data = readmatrix(F);
end

"I modified it to:"
Why do you need to create a second structure Z, when S already exists?

In your loop over files, check the isdir property to skip directories
for iFile = 1:numel(FileList)
if FileList(iFile).isdir
continue; % Skip files if they are a directory.
end
fullFileName = fullfile(FileList(iFile).folder, FileList(iFile).name);
Strings{iFile} = load(fullFileName);
end

OK, you didn't tell me you were going to load it into another cell array using the same index. If you had, I would have said to remove them like Stephen did, or else you can have a second counter index in the loop.
